Hyundai Heavy Industries unveils FLNG concept
Hyundai Heavy Industries (HHI) has completed the development of its own Hyundai floating liquefied natural gas (FLNG) plant model in association with Linde AG, an international industrial gases and engineering company of Germany, it was announced in January 2012.
T
he FLNG unit, existing only as a concept as for now, is a special floating vessel that can produce,
liquefy and offload natural gas directly to an LNG carrier. Aſter conducting conducted risk and
safety evaluations of the FLNG unit, HHI has also received approval-in-principle from Norway’s Det Norske Veritas (DNV). Te development of this FLNG concept
puts HHI in a unique position as the only company to date that can conduct engineering, procurement, installation and commissioning for both the topside and hull part. Te Hyundai FLNG unit will have an
annual production capacity of 2.5 million tonnes of LNG and can store about 193,800m3
compact size of 355m in length, 70m LNG within its relatively
in width and 35m in height. Te vessel consists of hull and topside facilities; and in addition to liquefaction and pre-treatment units, the topside also includes utilities such as a fresh water supply unit, an air compressor, heat source and power generation systems. Since the FLNG vessel concept
is
anticipated to take 25% less time to build compared to an onshore liquefaction and storage plant, the offshore plant represents an attractive option for oil majors and global shipping companies looking to commercialise stranded gas in offshore fields. “Hyundai FLNG [unit] has an efficient
and economical production capability in that it just takes about 45 months to build. Considering the fact that the need for the development of stranded offshore gas
Shell selects GE Oil & Gas for compressor supply
GE Oil & Gas has signed an enterprise framework agreement to supply compressors (used within the liquefaction process of natural gas) and associated services for Shell’s projects worldwide over the next six years. Under the agreement GE Oil & Gas, which provides technology and service solutions for the energy industry, will supply centrifugal compressors for key market segments such as LNG services, natural gas, refining and petrochemical applications.
GE says that it has also been contracted to supply two steam turbine-driven compressors for Shell’s Prelude FLNG project, offshore Australia. Addressing the space constraints associated with marinising equipment for use aboard floating LNG plants, the technology solutions provider is working to minimise the casings of the steam turbines and compressors in order to reduce both weight and footprint. The compression trains will be designed to cover a wide range of operating conditions, developing a technology for potential use in future floating LNG plants. Equipment covered under the agreement with Shell will be manufactured at GE Oil & Gas’ facilities in Florence, Italy, and Le Creusot, France. The deal will give Shell access to GE’s most advanced, high-tech compressor technology for deployment in the oil major’s key projects in high-growth regions, including Australia, West Africa, Russia and the Caspian region and Canada.
Prady Iyyanki, vice president, turbomachinery, GE Oil & Gas, says: “GE is committed to delivering enhanced value and efficiency to its global customers, including through the delivery of rigorously qualified and validated pre- engineered solutions that equate to faster execution in the pre- and post-order phases.”

fields is expected to be on the rise down the road, we will continue to step up our effort to win orders to build Hyundai FLNG [unit],” said Mr Kim Yoon-choon, senior vice-president of Hyundai Heavy’s Offshore and Engineering Division, who is in charge of the FLNG unit development project. As high oil prices and a steep increase
in demand for natural gas, triggered by the March 2011 Japanese nuclear disaster, boost the need for the development of offshore gas fields, the FLNG market is expected to grow further. In addition, HHI has been selected as
a core institute for the development of FLNG system engineering by the LNG Plant R&D center of KOGAS. Te goal of the project is to develop the Korean FLNG system by 2016. OMT
